Our client is looking for a MongoDB Developer to join their team on a six month initial contract, working three days a week onsite in London and rest remotely. This role is Inside IR35.

The MongoDB Developer is responsible for architecting, implementing, and optimizing scalable NoSQL data solutions across complex, distributed application environments. This role works closely with engineering, architecture, DevOps, cloud, and product teams to design high performance MongoDB schemas, enhance data accessibility, and ensure seamless integration with application services.

Essential skills/knowledge/experience:
* 6-10 years of professional software development experience in SQL and NoSQL, with at least 5 years focused on MongoDB.
* Thorough understanding of MongoDB architecture (Wired Tiger engine, BSON) and the conceptual differences between NoSQL and SQL.
* Proficiency in integrating MongoDB with backend runtimes such as Node.js/Express, Python/Django/Fast API, or Java/Spring Boot.
* Hands-on experience with AWS, Azure, or GCP environments for database hosting.
* Working experience on Data Modelling Tools with MongoDB Compass, Mongoose, or other ODM/ORM frameworks will be an added advantage.
